The addition of Bell, who started five games at right guard from Florida State last season and every game in 2015, has a particularly big impact on the interior personnel of Auburn's offensive line, which left spring with uncertainty at left guard.

"We're real excited about him," offensive line coach Herb Hand said before a meeting of the Nashville Auburn Club on Monday. "Obviously, he's started 20 games or so for a really good football program. He's going to bring a maturity level already. ... We expect him to come in and be a major contributor for us."

With the 6-foot-5, 320-pound Bell, a Mobile native, likely to stay at right guard it means there will likely be movement at left guard, which Hand called the "biggest piece of the puzzle" during spring practice.

"(Bell's) natural position is right guard; that's where he's been at and been comfortable," Hand said. "I'm just excited we got him. I think he's going to be a really good addition."

Redshirt-sophomore Marquel Harrell spent spring at left guard with the starters but either Mike Horton could move to the left side, where he split time in the spring, or Austin Golson could slide out a spot from center if Dunn were to come in and prove he could take over as the starter in the middle.

"We feel like we've got two or three guys that are battling for that spot there, but we need to leave (spring) with feeling good about five guys," offensive coordinator Chip Lindsey said on April 7, the day before Bell committed. "That's what coach Hand's kind of -- in his mind, he's like 'I'm trying different combination of guys at those spots to get the right guy.' But we're still looking for a guy or two to step up and be that next guy."

Hand said it is "not outside the realm of possibility" for Auburn's starting line to feature five seniors in left tackle Darius James, who still has to win a competition with Prince Tega Wanogho Jr. in fall camp, Golson, Dunn, Bell and Braden Smith.

"We're very excited about Wilson Bell, a veteran guy, very talented guy," Auburn coach Gus Malzahn said during an appearance on the Cole Cubelic show last month. "Braden, we moved him to tackle, felt like that transition went well. Austin Golson is a veteran guy that we have coming back. Of course, Darius James a returning starter at tackle too. It's good competition and we're excited and feel like we have the pieces up front to be successful."

Bell's December arrest for failure to appear related to a prior hit and run accident was not a deterrent in his coming to Auburn, which recruited the former Blount High School product in 2013. Bell did play for the Seminoles in the Orange Bowl.

"That was all stuff that our compliance and administration handles that stuff," Hand said. "I'm comfortable with it in meeting with him."

The addition of Dunn and Bell does mean Horton and Harrell could be in for another season of backup roles.

Hand knows there is still along time to go until any final decisions, but he likes having so many options.

"I want to have as much competition as possible," Hand said, "because ultimately if you have great competition, then people either when they win the job or it forces the other guys to up their game, ultimately Auburn wins."
